Abstract

The crushing plant in the mining industry produces noise levels above the allowable noise level, potentially causing hearing damage to mining workers. One way to early control this is by mapping the noise distribution in the area. The noise distribution mapping was based on noise intensity. The noise intensity measurement was done using a sound level meter according to Indonesian national standards 7231:2009. The noise exposure analysis was based on the NIOSH formula and Indonesia's national standard 7570:2023. The study's results revealed that noise levels at the source exhibited an intensity of approximately 95-103 dB. The noise propagation pattern extended from the southwest to the northeast, with an intensity of approximately 68-93 dB. The highest noise intensity was observed in the vicinity of the first jaw crusher, exceeding 100 dB, with a daily exposure time in this area of 6-12 minutes. Prolonged exposure to high noise levels can potentially lead to auditory damage. Therefore, the implementation of noise control measures, including using personal protective equipment and the installation of appropriate safety signage, is imperative.

Abstract

Municipal solid waste (MSW) generation contributes to methane emission, formed during anaerobic decomposition of organic. The MSW reduction can be forced into an integrated solid waste management site through 3R paradigm built in each municipal level area. This is because methane has a relatively short atmospheric lifetime of about 12 years compared to CO2. This means that reducing methane can quickly impact slowing global warming in the short term. This study aimed to achieve maximum results in reduction methane emission generated from an urban area through 3R waste treatment facility with measurable evaluation in 3 scenarios. The method used to gather the data analysis is Minitab 22 software, which forecasts an approach through trend method analysis, moving average, single exponential smoothing, and double exponential smoothing model to obtain the best-fit model for scenario analysis. The result showed that trend analysis has a high accuracy category with the smallest error (<10%: strong accuracy) in BaU, scenario 1, scenario 2, and scenario 3 with the MAPE value 0.002071 (0.2%), MAD value 0.00, and MSD value 0.00. Meanwhile, scenario 3 could decrease the amount of waste sent to landfills 188.03 tons/year in 2024 and 203.53 tons/year in 2033. Whilst, it could reduce methane up to 0.829126 tons-CO2-eq /year in 2024 and 0.897479 tons-CO2-eq /year in 2033 from total waste in Janti or 8-10% from the total methane emissions in Jabon landfill (65683,8 tons-CO2-eq /year). It concluded that optimizing the activities of 3R waste management facility units in each area, particularly in Sidoarjo, can significantly reduce the effect of methane emissions that arise in landfills.

Abstract

This paper discusses the relationship between changes in human activities and deforestation with the condition of pollutant concentration parameters in an area using the Google Earth engine (GEE) method. By applying the Systematic Literature Review method, it is expected to provide an explanation of changes in pollutant conditions, such as concentration patterns of CO, NO2, SO2, O3, HCHO, PM2.5, and PM10 as a result of changes in human activity and deforestation. Human activity patterns may change due to certain events or rules that force humans to follow them. A clear example is the lockdown event during the Covid-19 pandemic that resulted in restrictions on human activities, especially outdoor activities. Similarly, deforestation is the process of significant reduction of forest area through tree felling, forest burning, or other land use changes that result in loss of tree cover and alter forest ecosystems. Both of these events impact the environment and air quality in the region, such as affecting air pollution concentrations. In various studies, changes in human activities and deforestation have been shown to have a significant relationship and influence on air quality concentration parameters in a region.

Abstract

The transition from fossil-fueled vehicles into electric vehicles is considered to be a strategy that can significantly reduce emissions and improve urban air quality. This study aims to examine the impact of the battery electric vehicles growth in Semarang City on carbon emissions within the road transport sector. Projections were made to assess the long-term impact and contribution of this trend towards meeting government targets in 2030 and 2060. Low Emission Analysis Platform (LEAP) software was used to estimate carbon emissions based on amount of vehicle and vehicle kilometer traveled (VKT) data. Three scenarios were set: the BEV scenario, which focuses on the widespread use of electric vehicles, demonstrates a significant reduction, especially in PM10 emissions, highlighting the advantages of transitioning away from internal combustion engine vehicles. The EMX scenario, which emphasizes an energy mix plan to support electricity, does not demonstrate a significant reduction in emissions. The COM scenario, which combine the BEV and EMX scenarios achieves the lowest emissions overall, indicating that a comprehensive strategy is most effective for achieving long-term emission reductions. All scenarios indicate the need for more aggressive policies, technological innovations, and carbon capture strategies to achieve reduction targets, particularly in the road transport sector.

Abstract

The majority of tofu manufacturers lack the necessary infrastructure to treat wastewater, resulting in the direct discharge of wastewater into water bodies. Such practices have the potential to results in environmental pollution. This study examines the efficacy of combining anaerobic biofilter technology and pre-aeration with a microbubble generator for the treatment of wastewater generated by the tofu industry. The research focused on the impact of hydraulic retention time (HRT) on the reduction of pollutants, specifically chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS), and pH levels. The results indicated that prolonged HRT in the anaerobic biofilter significantly reduces pollutant concentrations. 48-hour HRT achieved reductions of 80.78% for COD, 78.53% for BOD, and 89.25% for TSS, respectively. The integration of a microbubble generator further enhanced treatment efficiency. The combination of a 48-hour anaerobic biofilter and a 180-minute microbubble generator achieved reductions of 93.82% for COD, 93.11% for BOD, and 97.5% for TSS. The effluent consistently met the pH quality standards set by the Indonesian government. The findings suggest the potential for optimizing retention times and combining anaerobic and aerobic treatments to address wastewater challenges in the tofu industry.

Abstract

Urbanization and climate change are expected to exacerbate and introduce uncertainty in future flood characteristics. The city of Denpasar often experiences flooding due to rapid population growth and changes in land use. One form of flood mitigation that can be implemented is infiltration wells. This research aims to design infiltration wells as an environmental conservation effort by evaluating the characteristics of the watershed and the depth of groundwater. This research will also examine lithological aspects and use geographic information systems (GIS) to increase effectiveness in planning. The research results show that the construction of infiltration wells at the research location is effective in reducing flood volume, with reductions varying between 19.86% in South Denpasar and 59.58% in North Denpasar, East Denpasar and West Denpasar. Infiltration wells not only reduce the risk of flooding but also play an important role in preserving the environment according to the Tri Hita Karana concept. By integrating these sustainable practices into spatial planning, water resource management can be enhanced, fostering a healthy environment for future generations.
